PASTE FEEDER Filed Feb. 1930 .el Jua btQmmg i A Patented pr. 12, 1932 UNITED I,STATES HERBERT N. ALLmsoN, or SOUTH 'OBANGENEW' JERSEYY PASTE FEEDER Application ynea February 27, 1930. *ser1a1no.;431,65s.

The main object of this invention is to prvide a preferred type of dispenser using a tubular cylinder in which a screw is mounted, the screw reciprocating a ball in said cylinder in such manner that a portion of the periphery of the ball will expel a quantlty o f paste froma tube located in the body.

Another object of the invention 1s to provide a modied type of paste dispenser, comprising a cylinder body in which a ball 1s projected against a filled tube of paste by va spring, so that a quantity of paste may be expelled from the tube.

The above and other objects will become apparent in the description below in which characters 0f reference refer to like-named parts in the drawings.

Referring brieiy to the drawings, Figure 1 is a` longitudinal partially sectioned front elevational view of the preferred type of dispenser.

Figure 2 is a top plan yiew of Figure 1.

Figure 3 is a cross sectlonal view taken on line 3 3 of Figure 1. i

Figure 4 is a longitudinal partially sectioned front elevational view of the modified type of dispenser.

Figure 5 is a top plan viewrof Figure 4.

Figure 6 is a cross sectional'view of the modied type of dispenser taken on line 6-6 of Figure 4. Referring in detail to the drawlngs, the numeral 10 indicates a longitudinal hollow body. A straight longitudinal slot 11 extends the length of the body for a purpose which Will be more fully hereinafter described. At the upper end, the body is closed by a cap 12 and at its opposite end a similar cap 13 covers the lower opened end of said body. The

0 upper cap 12 is provided with an aperture 14, through Which a spout 15 of a tube of toothpaste or shaving cream 16 extends. Thev tube 16 is entirely housed withinthe tubular body and the lower end thereof 1s normally l in flattened condition as indicated by the nunumeral 17.

The threaded stem 18 extends axially throughout the entire length of the body 10 and has its ends rotatably anchored in the caps 12 and 13. The lower end of the threadtube of paste. At one position near the upper ed stem .18 extendsout of the Ycap 13.' Tothis i end a knurled manipulating disc 19 isfhse# cured. y

` Aaball 20. is provided with a threaded diametrical opening and engages thethreaded stem118. This ball is of'suiiicient diameter to'exert a pressure againstthe filled portion of lthe tube 16, when said vtube is tobe expelled offits contents.V A guide pinl 21 juts outwardly from the periphery of the sphere or ball 2O and registers in the slot 11heretofore mentioned asextending longitudinally inthe'bodylO. In'the modified form of device shown in Figures 4, 5 and 6, a sphere 27 is yieldably mounted upon a spring 29 which rests upon a cap 30. This cap closes the-lower end of a tubular body 22. At the upper endof the body 22,-a second closure cap 28 is mounted.

:Thiscap 28 is Ialso providedwith an aperture so, that thespout 25 ofal tube. of toothpaste or shaving cream 24 may project.v TheflattenedV end 26 of the tube 24 of the paste rests beneath the surface of the ball 27.

A longitudinal channel 23 is formed lengthwise in the body 22 of the `modified form of device and permits a portion of the surface of the ball 27 to project out thereof so that this ball may be rolled over the lled end ofA each of the tubular bodies 10 and 22 in the preferred and modified types of dispensers respectively, a shoulder 31 is formed f which has a substantially curved surface. This curved surface has 'a limiting member for preventing displacing atube of paste 16 have their lower closed ends substantially flat- 'l tened and are sold in this condition. In the preferred type of device, shown in Figures 1, 2 and 3, a ball 20 is adapted to be reciprocated by a threaded stem 18, said ball threadedly engaging a knurled disc 19. The stem 18 being secured to this disc is rotated and said stein engaging said ball 20, moves this ball upwardly against the filled portion of the tube 16. This eXpels a quantity of paste from the spout l5. In the modified type of device, a ball 27 also abuts the lled portion of the tube 24 but in this type the ball is urged against the iilled portion of the tube 24 by manipulation of said ball by the lingers through the channel 23. As the ball is moved upwardly in the body 22, a spring 29, upon which the ball is seated supports .the latter and prevents the same from falling.

It is to be noted that certain changes in form and construction may be made without departing `from the spirit and scope of the invention.

I claim:

l. lIn a dispenser, a hollow body adapted to receive a paste tube therein, a ball Inovable in said body, said body having a channel therein, a portion of said ball protruding thru the said channel and a coil spring supporting said ball, Vfor lifting said ball into extruding contact with said tube.

2. In a dispenser, a hollow body adapted to receive a paste tube therein, a ball movable in said body, said body having a channel therein, a portion of said ball protruded thru the said channel and a yieldable spring supporting said ball, said ball being raised by said spring to contact position with said paste tube. Y A V In testimony whereoi:l I aix my signature.
